Alex Hofmann will have to wait and see whether he is fit to resume his season at the Czech Republic Grand Prix as doctors continue to monitor his recovery from severe hand injuries sustained at Laguna Seca.

Already nursing a break in his right hand, the German was bundled down the road by Sylvain Guintoli in practice for the United States Grand Prix, and required three hours of reconstructive surgery - involving a metal plate and fifteen screws - to repair broken metacarpus.

The procedure came with a five-week rehabilitation period, leaving Hofmann short of making Brno next weekend, but he is anxious not to lose any more track time.

"The specialists in Europe have confirmed that the operation was performed very well," he told adrivo.com, "The swelling has gone down and the stitches came out on Friday [3 August], so I can now start to rehabilitate. The first thing to do is try to get weight on the hand and mobility in the fingers, but the tendon in my middle finger was badly damaged, however, so we have to keep an eye on how it heals."

Chaz Davies, who subbed for Hofmann at short notice at Laguna Seca, remains on stand-by for Brno, and has clearance from his AMA Supersport team to compete if necessary, but the German is keen to return.

"I don't know if it is possible to return," he admitted, "At the Sachsenring, I rode with a hand that was only 50 or 60 per cent. That one is now 100 per cent, but the other hand is a longer story. I have had two to three weeks doing nothing with it at all, but I will not sit on a bike again until I am 100 percent fit. I have now had a lot of injuries in short time and I want to know that I really can attack when I return."
